Staying in Touch
Staying in Touch — What to Use, Where, and What It Ought to Cost
Somewhere between the old horror of the hotel telephone and the modern horror of the roaming bill, a sensible middle has appeared. It is not complicated. It only looks complicated because every company involved would rather you did not think about it too carefully.
So let us think about it carefully, and then put it out of mind for the rest of the trip.
Use the phone you already own
Your telephone works abroad. It will simply charge you for the privilege, and the charge arrives three weeks later when you have forgotten why you made the call. A day pass from an American carrier runs somewhere around twelve dollars a day; a pay-as-you-go rate without one can be several dollars a minute and a couple of dollars a text. Ten days in Portugal on a day pass is a hundred and twenty dollars before you have bought a single coffee.
And yet — sometimes you should just pay it. The rental desk in Palermo has your car and no email address. The clinic wants to reach you about your mother. The airline's rebooking line will not answer a WhatsApp call, and the hold music is forty minutes long. These are not moments to be economising over a dollar a minute. Use the phone. Make the call. The bill is the cheapest part of the problem.
Use WhatsApp for everything else
WhatsApp, iMessage, Signal, FaceTime — all of them travel over data rather than the carrier's meter. A voice call to your daughter from a café in Kyoto costs whatever the data costs, which is close to nothing. Over the hotel's wi-fi it costs nothing at all.
This is where most travelers' bills quietly disappear. The evening call home, the photographs to the group, the ten-minute conversation with the friend who is meeting you in Lisbon on Thursday — none of that needs the cellular network. Do it at the hotel, over breakfast, in the lounge, on the ship's wi-fi if it is decent.
A word about the hotel's network
Hotel wi-fi is a shared room with the door propped open. WhatsApp and Signal are encrypted end to end, so the contents of those conversations are not the worry. The worry is everything else you do while connected to it — the bank, the airline account, the tax document you meant to look at.
Two habits cover nearly all of it:
- Turn off automatic joining. A network named Hotel_Guest_Free is trivially easy for anyone in the lobby to imitate. Ask at the desk which network is theirs, join that one, and tell the phone to forget it when you leave.
- Do the sensitive things on cellular data, not on their wi-fi. Your own data connection is between you and the carrier. Banking, boarding passes, anything with a password worth stealing — do it there. It costs a few megabytes. It is the best money you will spend all week.
A VPN is a reasonable third habit if you already use one. If you do not, the two above will serve you honestly.
So yes — carry a data card
An eSIM is not a luxury and not a gadget. It is the thing that keeps you off the hotel network when it matters, and off the roaming meter when it does not. You buy it before you leave, it activates when you land, and the phone simply works.
The arithmetic is not subtle. A regional eSIM covering most of Europe for a fortnight tends to run somewhere between ten and thirty dollars depending on how much data you take. The same fortnight on a carrier day pass is a hundred and sixty-eight. The difference buys a very good dinner in Bologna.
What it is good for, in practice:
- Maps in a strange city. The single most useful thing data does. Walking from Termini to the flat with the phone in hand, at nine at night, in the rain.
- The taxi and transport apps. Bolt in Tallinn, Grab in Bangkok, FreeNow in Dublin — all of them want a live connection at the kerb, which is exactly where there is no wi-fi.
- The calls you would rather not make on the hotel's network. The bank, the card company, the two-factor code that decides whether you can pay for anything.
- The moment something goes wrong. A cancelled flight at eleven at night is not the time to be looking for a password on a scrap of paper behind the reception desk.
The one thing an app cannot do
Some things still need a real telephone number. Your bank's verification text will go to your home number, not to WhatsApp. So will the airline's gate change, the pharmacy, and the hire company. Keep your home line active for receiving those messages even while the data runs through the eSIM — most phones will hold both at once, and it costs nothing to receive.
This is the part travelers get wrong most often: they swap the SIM out entirely, land in Athens, and discover their bank will not let them buy a train ticket because the code went to a card sitting in a drawer in Ohio.
The whole of it, in four lines
- Talk to home on WhatsApp, over the hotel's wi-fi, for nothing.
- Keep the bank and the boarding passes off that wi-fi and on your own data.
- Carry an eSIM so that data is cheap enough not to think about.
- When something truly matters, make the ordinary telephone call and pay the ordinary price.
Connection should be the quietest part of the journey.
A note on figures
Roaming charges, day-pass prices, and eSIM rates change often and vary by carrier and destination. The numbers above are indicative of what travelers were paying at the time of writing; check your own carrier's current rate before you leave. Data cards we keep on hand are listed on our Resources page.
